A Comparative Study Between Infraclavicular and Axillary Blocks for Assessment of Motor Power Using Handgrip Dynamometer

Hand Surgery is surgery of the hand, the wrist, and the peripheral nerves of the upper limb. Many different types of surgeries can be performed on the hand, depending on the underlying cause of the problem such as Closed reduction and fixation, Tendon repair, Skin grafts, Skin flaps, Carpal Tunnel Release, and ganglion removal. Hand surgery is usually associated with marked postoperative pain. Ultrasound-guided regional anesthesia is usually performed in patients undergoing hand surgery. This study aims to compare Ultrasound-guided infraclavicular block and axillary block and assess the degree of motor power and duration by testing hand grip strength using a hydraulic hand dynamometer in patients undergoing hand surgery. Objectives: To determine the degree of a motor block using a hydraulic hand dynamometer. To Estimate time needed to regain full motor activity. To identify whether ultrasound-guided axillary block may preserve motor function to a greater extent than infraclavicular blocks.
